Aerospace and defense contractor Orbital ATK recently tested a hypersonic engine combustor at NASA's Langley Research Center.

The tests were successful; the component met or exceeded all requirements needed for a hypersonic flight mission. Read more at 3DPrint.com: http://3dprint.com/116380/orbital-at...rsonic-engine/
